The last compound is the first 6,8-cycloeudesmane of marine origin. It has been isolated from Laurencia microcladia collected in the Bay of Calenzana, Elba Island, Italy (Guella et al, 2002, 2003). For a summary of the NMR results for polyhalogenated sesquiterpenes of Laurencia, see Gonzalez et al. (1979b).

A culture of the Ascomycete Penicillium rugulosum isolated from the sponge Chondrosia reniformis collected on Elba Island, Italy, produced a series of prugosenes. The biosynthesis of these polyketides has been established by labeling. Some of these original derivatives contain an oxabicydo[2.2.1]heptane, which is rarely encountered in natural products. However, none of these derivatives seems to show any particular biological activity (Lang et al, 2007).

This ore occurs both in the primitive and secondary rock it abounds in the Island of Elba, Norway, Sweden, and, Switzerland. Pine specimens ore mot with in the fissures of rooks in the volcanic districts. 

Silicic volcanics occur as lavas at San Vincenzo, Roccastrada, Monte A-miata, Monti Cimini and Tolfa-Manziana-Cerite complex. Pyroclastic rocks are scarce or absent, and a few ignimbrites only occur at Monti Cimini and Cerite complex. Silicic intrusions crop out in the islands of Elba, Montecristo and Giglio, and at Campiglia and Gavorrano in southern Tuscany. Other granitoid bodies occur as seamounts in the northern Tyrrhenian Sea (e.g. Vercelli Barbieri et al. 1986) and as hidden intrusions in several places of southern Tuscany (e.g. Franceschini et al. 2000 Poli et al. 2003).

The fungus Penicillium rugulosum was isolated from the sponge Chondrosia reniformis collected off the island of Elba, Italy. Chemical investigation yielded a series of structurally unusual tricyclic and bicyclic pentaenes, pnigosenes A1 (2), A2 (3), A3 (4), B1 (5), B2 (6), Cl (7), and C2 (8). ... 

The crystal structure of a natural sample of a 2M2 lepidolite (a mica-type mineral) from the island of Elba (Italy) has been determined by singlecrystal X-ray diffraction techniques and compared with that of a second 2M2 lepidolite from Rozna (Czechoslovakia) and other related structures. The two sets of unit-cell parameters are collated in Table 38. The most interesting features which emerge from the comparison are the constant presence of remarkable octahedral ordering and the almost identical composition of the tetrahedral sheets (Elba Si3 3oAlo.64 Rozna Sis soAlo.ei)... 

Returning to Napoleon s hairs Italian physicists made a concerted effort to study them in 2008. They used a scientific method called neutron activation analysis the sample was irradiated with neutrons for some time (a nuclear reactor is usually needed for this), which caused the formation of short-lived radioactive atoms, the amounts of which could be easily measured without actually destroying the object being studied. An advantage of this method is that very small amounts of elements can be detected. The particular hairs were carefully selected in this study. Contemporary human hairs were chosen randomly. From museums around Europe, the scientists obtained hairs both from King of Rome Napoleon II (1811-1832) and empress Josephine (1763-1814), the son and first wife of Napoleon Bonaparte, and of course from Napoleon himself, not only from the island of Saint Helena, bnt also form his childhood (age of 1) in Corsica and from the island of Elba, the scene of Ms first exile. The arsenic content of these samples is shown in Table 4.2.
